编制一个程序，在窗体上放一个Text1，text2，text3；
要求：
在这个程序运行时，把它最小化到后台，当别的程序在前台运行时，按键盘的“F2”，能使程序的Text1里的内容直接粘贴到当前程序的文本框里；按键盘的“F3”，能使程序的Text2里的内容直接粘贴到当前程序的文本框里；按键盘的“F4”，能使程序的Text3里的内容直接粘贴到当前程序的文本框里.



比如在文本框里输入111111
运行记事本，按“F2”直接粘贴出111111

以下代码，只可以在窗口里有一个text时，可以实现这个功能，可是现在需要有三个text，对应三个热键F2 F3 F4都可以使用，如何更改啊，大家帮我看看！

窗体的代码：
Option Explicit

Private Sub Form_Load()
Dim ret As Long

'记录原来的window程序地址
preWinProc = GetWindowLong(Me.hwnd, GWL_WNDPROC)
'用自定义程序代替原来的window程序
ret = SetWindowLong(Me.hwnd, GWL_WNDPROC, AddressOf Wndproc)

idHotKey = 1
uVirtKey = vbKeyF2
ret = RegisterHotKey(Me.hwnd, idHotKey, Modifiers, uVirtKey)
End Sub

Private Sub Form_Unload(Cancel As Integer)
Dim ret As Long
'取消Message的截取，使之送往原来的windows程序
ret = SetWindowLong(Me.hwnd, GWL_WNDPROC, preWinProc)
Call UnregisterHotKey(Me.hwnd, uVirtKey)
End Sub

Private Sub Text1_Change()

End Sub

模块1的代码：
Option Explicit

Declare Function SetWindowLong Lib "User32" Alias "SetWindowLongA" (ByVal hwnd As Long, ByVal nIndex As Long, ByVal dwNewLong As Long) As Long
Declare Function GetWindowLong Lib "User32" Alias "GetWindowLongA" (ByVal hwnd As Long, ByVal nIndex As Long) As Long
Declare Function CallWindowProc Lib "User32" Alias "CallWindowProcA" (ByVal lpPrevWndFunc As Long, ByVal hwnd As Long, ByVal Msg As Long, ByVal wParam As Long, ByVal lParam As Long) As Long
Declare Function RegisterHotKey Lib "User32" (ByVal hwnd As Long, ByVal id As Long, ByVal fsModifiers As Long, ByVal vk As Long) As Long
Declare Function UnregisterHotKey Lib "User32" (ByVal hwnd As Long, ByVal id As Long) As Long

Public Const WM_HOTKEY = &H312
Public Const MOD_ALT = &H1
Public Const MOD_CONTROL = &H2
Public Const MOD_SHIFT = &H4
Public Const GWL_WNDPROC = (-4)

Public preWinProc As Long
Public Modifiers As Long, uVirtKey As Long, uVirtKey1 As Long, idHotKey As Long
Private Type taLong
ll As Long
End Type

Private Type t2Int
lWord As Integer
hWord As Integer
End Type

Public Function Wndproc(ByVal hwnd As Long, ByVal Msg As Long, ByVal wParam As Long, ByVal lParam As Long) As Long
Dim KeyStr As String
KeyStr = frmMain.Text1.Text
If Msg = WM_HOTKEY Then
If wParam = idHotKey Then
Dim lp As taLong, i2 As t2Int
lp.ll = lParam
LSet i2 = lp
If (i2.lWord = Modifiers) And i2.hWord = uVirtKey Then
SendKeys KeyStr
End If
End If
End If
'如果不是热键信息则调用原来的程序
Wndproc = CallWindowProc(preWinProc, hwnd, Msg, wParam, lParam)

End Function

用Private Declare Function GetAsyncKeyState Lib "user32" (ByVal vkey As Long) As Integer

请版主说明白点好吗？急啊~~谢谢了~你说的我没看懂啊？

我说热键用这个API

Private Declare Function GetAsyncKeyState Lib "user32" (ByVal vkey As Long) As Integer

厄……GetAsyncKeyState 似乎只能用来检测键状态的，不是热键。

可以达到热键效果，，，，当检测到某键点击然后sendkey就可以。

怎么把你的保存了也运行不了？你设置uVirtKey为变量可以不。。。好象，，不行。。

你查下这个：
Private Declare Function GetAsyncKeyState Lib "user32" (ByVal vkey As Long) As Integer

的用法就知道了。这个要用timer检测，，，那个好象不用？
